如何在Plotly Dash中动态实现ListGroupItem的ListGroup？

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.ListGroup(id='list-group'),
    html.Button('Add Item', id='add-item-button', n_clicks=0)
])

@app.callback(
    Output('list-group', 'children'),
    [Input('add-item-button', 'n_clicks')]
)
def update_list_group(n_clicks):
    items = []
    for i in range(n_clicks):
        item = dcc.ListGroupItem(f'Item {i+1}')
        items.append(item)
    return items

if __name__ == '__main__':
    app.run_server(debug=True)
